You would have to think that the Undisputed King for (take-out/to go) would be Burgers ;what with the millions of folks going in ; and/or driving through daily .(?) But a Sub still has the edge on the healthy-choice issue . Asian take-out is a pretty heavy hitterin its own right ... and one of my personal favorites !

My top takeout food choice would be a gyro sandwich or plate. Tried making them at home once...never again. Second choice would be real Mexican takeout. Now I must try those Freddy's tacos mentioned by other commenters.
